    The VEX Cortex Microcontroller coordinates the flow of all information and power on the robot. It has built in bi-directional communication for wireless driving, debugging and downloading using the state of the art VEXnet 802.11 wireless link. The Microcontroller is the brain of every VEX robot.

    Features
    Built-in VEXnet Technology: Wireless driving, wireless debugging, and wireless downloading
    Motor Ports: (8) standard 3-wire Motor or Servo ports. (2) 2-wire Motor ports
    I2C Smart Sensor Port: Will connect to multiple new smart sensors in the future
    UART Fast Serial Ports: Connects to the VEX LCD Display (19,200 baud) and will have future support to 1.125 Mbaud
    Digital/Analog Input Ports: (8) high-res Analog Inputs, (12) fast Digital I/Os that can all be used as interrupts
    Rx1 and Rx2 Ports: Also support for two 75MHz crystal transmitters and receivers
    Battery Ports: Connect 7.2V power sources, such as the Battery Holder or the VEX 7.2V Robot Battery. Also connect a 9V Backup Battery to protect against communication losses.
